The scorer may have put in some extra time at the 18-meter Nationals to
get this squared away, but I recall seeing a number of competitors' IGC
files posted online in July, and some did, others didn't include a
contest number in the "Glider ID" Field.

As it happens, "Glider ID" is the data field IGC Technical Specs for FRs
have for years defined as a mandatory "Header Record" for ""the unique
registration alphanumeric of the individual aircraft." Given some
variation among FR models, the data will appear at IGC file line 6 or
thereabouts, preceded by "HFGIDGLIDERID:".

The next ten or so IGC file lines are reserved for other mandatory Header
Records and below these, Tech Specs provide for a "Competition ID" line,
starting with
"HFCIDCOMPETITIONID:" This is an optional data field, but most FRs DO
provide for it.

Perhaps some new equations need to be added, but scoring programs - like
the spreadsheet I use for claim evaluation - can parse out anything
that's in a predictable place and/or marked by clear identifying text.
